Introduced as a prototype one year ago, and displayed at DoCoMo’s booth during the last CEATEC 2008, Fujitsu officially announced their latest wonder, the Separate Keitai F-04B, today during a Press Conference in Roppongi….

The F-04B is a “new type” of Keitai that can be separated in two parts: Display Unit and Keyboard Unit connected via Bluetooth (each part features a Lithium Ion battery)… To put it simple, Users will be able to use it as they want since the screen part features an LCD Touch screen of 3.4-inch.

For example, you can use only the screen part to watch movies, listen to music, send mail, watch TV (1Seg) and keep the QWERTY keyboard part in your bag. Regarding the Keyboard unit, it can be used as a keyboard (of course), microphone, Speaker device, game pad…
And to please Japanese Customers, Fujitsu also offers the possibility to attach both parts together in order to use it as a classic Slide phone since we’re talking about a dual Keyboard Phone…

But, probably the most interesting feature that caught our attention was this optional projector unit. With a brightness of 6 lumens, users will be able to project movies, pictures, games… It features an 800 mAh Battery with 2 hours of lifespan (at the highest Luminance), as well as Texas Instruments Inc’s second-generation “DLP Pico” chipset, and it provides a resolution of 854 x 480.
To be able to use it, Users will have to replace the Keyboard Unit with this Projector Unit, and use the keyboard as a real remote control…

Anyway, Fujitsu presents this Keitai as a real all-in-one solution and announces to target 20 -30 years old Japanese people…

Our impression:
The F-04B is a nice All-in-One phone, little bit bulky, but different from what we used to see in Japan (Clamshell phone)… Bulky, but when you divide your phone into two parts, you have a quite sleek and light display Unit that can be used without the Keyboard Unit…
Regarding the overall quality, we have something well built and quite stylish. The game pre-loaded on the phone displays nice graphics. The Camera module, a 12.2Mpix camera, is not bad and takes nice pictures for a phone.
We like the idea of a separated QWERTY keyboard allowing the user to type mails, or use it as a Game Pad, or a remote control. The projector, even if it’s still a “gadget”, is really interesting, and should be enough to display a movie on your ceiling when you are in your bed…

However, we are a little bit disappointed by the LCD touchscreen… It’s accurate, but not really responsive… It is also unfortunate that Fujitsu did not think of a solution to use the QWERTY keyboard on the train. Indeed, nothing is expected to maintain the screen when you’re typing your email …

Anyway, even if the screen is not perfect, it should be way enough to enjoy multimedia, mail, internet….
